TROUBLE SHOOTING CAUSE ACTION
Poor performance or lack of
power.
Low air pressure. Ensure that the air pressure is correct at 90psi, max 100psi.
If tool has been left for some time without use, the oil
may dry out slightly, causing a sticky residue.
Strip tool down, clean and re-oil.
Needles worn or some missing. Replace with new set of needles and new needle holder.
Piston seal worn. Remove seal from piston and fit into bore of cylinder. If it
drops to the bottom of the bore, a replacement is required.
Incorrect chisel fitted. Ensure that the chisel is for a vibration reduced tool.
Valve pin broken. Replace valve pin and 6mm plastic ball.
Tool continues to run with
trigger released.
Valve seal may have become dislodged through the tool
being disconnected with the trigger in the open position.
Ensure that the trigger has not been taped or wired in the
open position, reposition or replace valve seat o'ring.
High vibration.
High air pressure. Ensure that the air pressure is correct at 90psi, max 100psi.
Lack of lubrication. Lubricate with the recommended air tool oil daily.
Low air pressure 70-80psi can also cause high vibration. Ensure that the air pressure is correct at 90psi, max 100psi.
Front return spring weak or broken. Replace return spring.
Guide plate seal worn. Replace guide plate seal.
Piston cushion failed. (This is a split o’ring) Replace with a new piston cushion.
6mm plastic ball worn out. Check for and remove the remains of the ball, possibly in
an exhaust hole of cylinder and renew 6mm plastic ball.
Valve pin broken. Replace valve pin and 6mm plastic ball.
Tool stopped working.
Noise Levels Noise level measured in accordance with: EN ISO 15744: 2008
Vibration Levels Vibration measured in accordance with: EN ISO 28927-9:2012
and EN ISO 20643:2005. (k) Equals the factor of uncertainty, which allows for
variations in measurement and production. Vibration Data figures are tri-axial,
which gives the total vibration emission. Because of various factors, the range of
vibration from these tools may vary between -0% +40%. The vibration is
dependent on the task, the operators grip and feed force employed etc.
NOTE: The above vibration levels were obtained from tri-axial measurements to
comply with the requirements of “The Control of Vibration at Work Regulations
2005*” and the revisions to the (8662) now EN ISO 28927-9:2012 and EN ISO
20643:2005 series of standards. These values are at least 1.4 times larger than
the values obtained from single axis measurements.
*Based on European Union Council Directive 2002/44/EC (Physical Agents
(Vibration) Directive)).
Risk of Hand Arm Injury
Because of various factors, the vibration from this range of tools may be between
3.7 m/s

The vibration is dependent on the task, the operators grip, and feed force
employed.
